RiGht-haNd KeyS aNd KNobS

The RNG Key allows the pilot to select the desired maprange. Use the up arrow o the key to zoom out to a largerarea, or the down arrow to zoom in to a smaller area.

The Direct-to Key provides access to the direct-tounction, which allows the pilot to enter a destinationwaypoint and establishes a direct course to the selecteddestination.

The MENU Key displays a context-sensitive list o

options. This options list allows the pilot to accessadditional eatures or make settings changes which relateto the currently displayed page.

The CLR Key is used to erase inormation, removemap detail, or to cancel an entry. Press and hold the CLRkey to immediately display the Deault NAV Page.

The ENT Key is used to approve an operation orcomplete data entry. It is also used to confrm inormation,such as during power on.

The large right knob is used to select between thevarious page groups: NAV, WPT, AUX, or NRST. Withthe on-screen cursor enabled, the large right knob allowsthe pilot to move the cursor about the page. The largeright knob is also used to move the target pointer right(turn clockwise) or let (counterclockwise) when the mappanning unction is active.

The small right knob is used to select between the

various pages within one o the groups listed above. Pressthis knob momentarily to display the on-screen cursor.The cursor allows the pilot to enter data and/or make aselection rom a list o options. The small right knob isalso used to move the target pointer up (turn clockwise) ordown (counterclockwise) when the map panning unctionis active.

The CDI Key is used to toggle which navigation source(GPS or VLOC) provides output to an external HSI or CDI.

The OBS Key is used to select manual or automaticsequencing o waypoints. Pressing the OBS Key selectsOBS mode, which retains the current active to waypointas the navigation reerence even ater passing the waypoint(i.e., prevents sequencing to the next waypoint). Pressingthe OBS Key again returns the unit to normal operation,

with automatic sequencing o waypoints. When OBSmode is selected, the pilot may set the desired course to/rom a waypoint using the Select OBS Course pop-upwindow, or an external OBS selector on the HSI or CDI.

The MSG Key is used to view system messages and toalert the pilot to important warnings and requirements.

The FPL Key allows the pilot to create, edit, activate,and invert ight plans, as well as access approaches,departures, and arrivals. A closest point to ight plan

eature is also available rom the FPL Key.The PROC Key allows the pilot to select and remove

approaches, departures, and arrivals rom the ight plan. When using a ight plan, available procedures or thedeparture and/or arrival airport are oered automatically.Otherwise, the pilot may select the desired airport, thenthe desired procedure.

6) For precision approaches and some non-precision approaches, a reminder windowappears indicating that GPS guidance onsuch approaches is strictly or monitoring only use the VLOC receivers and external CDI(or HSI) or primary navigation. To confrm thisreminder, highlight Yes? and press the ENTKey.

Not all approaches in the database are approved or GPSuse. As the pilot selects an approach, a GPS designation

to the right o the procedure name indicates the procedurecan be own using the GPS receiver. Some proceduresdo not have this designation, meaning the GPS receivermay be used or supplemental navigation guidance only.ILS approaches, or example, must be own by tuning the

VLOC receiver to the proper requency and coupling theVLOC receiver to the external CDI (or HSI).

A selected approach may be activated or loaded. Once

an approach is selected, it may be activated or navigationrom the Procedures Page. Activating the approachoverrides the enroute portion o the active ight plan,proceeding directly to the approach portion (or a ullapproach, directly to the initial approach fx). Activatingthe approach also initiates automatic CDI scaling transitionas the approach progresses.

In many cases, it may be easiest to Load the ullapproach while still some distance away, enroute to the

destination airport. Later, i vectored to fnal, use theollowing steps to select Activate Vector-To-Finalwhichmakes the inbound course to the fnal approach fx (FAF)waypoint active. Otherwise, activate the ull approachusing the Activate Approach? option.

GUideLiNeS foR fLyiNG aN appRoaCh

Due to the variety o available approach procedures,the specifc steps required will vary according to theapproach selected. Keep the ollowing general guidelinesin mind while ying the approach:

The pilot will typically select the destination airportas the last waypoint in the active ight plan orusing the Direct-to Key. Doing so ensures that

the desired waypoint will automatically appearwhen choosing the Select Approach? option romthe Procedures Page. (Otherwise, frst choose theairport, then the approach procedure.)

When a localizer-based approach (such as an ILS)is loaded, the desired requency is automaticallyplaced in standby on the VLOC window. Toactivate the requency, press theVLOC Flip-fopKey.

If the VLOC receiver will be used for the approach,

be sure to switch the external CDI (or HSI) toVLOC by pressing the CDI Key (VLOC willappear directly above the CDI Key; see page 15).

An Auto ILS CDI setting provides automaticswitching to VLOC once established inbound onthe fnal course segment o an approach.

As the aircraft progresses to each approachwaypoint, a waypoint alert message (NEXT DTK

# # #) will appear in the lower right corner othe display (see page 15).

When the pilot should begin a course change (via astandard rate turn), turn advisories (TURN TO ## #) will appear in the lower right corner o thedisplay (see page 15).

For GPS-based approaches, receiver autonomousintegrity monitoring (RAIM) will monitor

satellite conditions and alert the pilot usingan INTEG or WARN annunciation at thebottom let corner o the display (see page 15)i protection limits cannot be maintained. Ithis occurs, the GPS receiver should not be usedor primary navigation guidance. Revert to analternate navigation source, or select an alternatedestination airport.

Within 30 nautical miles of the destination airport,CDI scaling will transition rom 5.0 nauticalmiles (enroute mode, ENR) to 1.0 nautical mile(terminal mode, TERM) or when leaving thedeparture airport, rom 1.0 nm to 5.0 nm. Within2.0 nautical miles o the fnal approach fx, GPS-based approaches will see a second transition rom1.0 nautical mile to 0.3 nautical mile (approachmode, APR).
